Design And Implementation Of Equipment Performance Data Monitoring And Analysis System Of WLAN

With the development of wireless local area network (referred to as WLAN) technology matures, and the rapid growth of demand for network bandwidth mobile users,To meet user demand for bandwidth, WLAN network has been the major operators of commercial means to do triage data traffic.In order to better provide WLAN services, so that he can run an efficient, open, heterogeneous, cross-platform network management system will be put in the focus of the next step.This paper focuses on the WLAN NMS device data monitoring and analysis system has been designed and developed, achieve a WLAN access network, the routing device, data acquisition, operation monitoring, and other functions. real-time monitoring device data link off, dynamic services running.The system is based on the SNMP protocol, based on the analysis and design of the logical view of the system architecture and the functionality of the device to complete discovery and data acquisition and processing,In this system,users can discover routing devices within the network based on the address range to set the IP address range,on this basis,according to the SNMP protocol and related technologies MIB repository of information collected on the device and operating information on these devices, through histogram, line charts and tables, etc. display and intuitive way, so that the system has good visibility and ease of management.This paper is unwound from the following four aspects:First, the background of the project, significance, research status were introduced, meanwhile the mainly work and organizational structure were introduced in this paper.Secondly, the relevant technical theory used herein SNMP protocol, SSH framework, three-tier architecture and technology JFreeChart simple elaboration.Again, the equipment data monitoring and analysis system as a whole needs analysis, and were divided into various sub-systems of the various sub-functions of the needs analysis, and based on the various functions of the database design has been designed, and add each table in the database.Finally, the WLAN network equipment performance data monitoring and analysis system design and implementation. First described the overall design goals and overall architecture design equipment performance data monitoring and analysis system, and from the SNMP business operations, network monitoring configuration, network operation monitoring, performance statistics and analysis of these four subsystems of the system design and code.
